Obesity: a diet that is acceptable is more likely to succeed.

Obesity is a serious and increasing public health problem in the UK. The author discusses current evidence which suggests that intervention with individual clients is worthwhile, and that the priorities for promoting a healthy body weight are to reduce dietary fat and eat a diet high in carbohydrates, in conjunction with moderate daily physical activity. The client is unlikely to achieve an maintain a healthy body weight unless they find a diet and forms of exercise that they enjoy. Health professionals can help by providing evidence-based advice tailored to the individual client's preferences. For example, clients can eat more of the fruits and vegetables they like, and sugar need not be excluded from the carbohydrate components of the diet and may be beneficial in making the diet more palatable. Slow, steady weight loss should be the aim leading to maintaining a healthy body weight in the long-term. Small acceptable changes to the diet, which can be maintained lifelong, should be encouraged. Some practical suggestions for low energy diets and ways of increasing exercise are included.
